    My hydrometer i believe got tossed when I got the refractometer and noticed it was way off. So I calibrate it before I use it every time, takes me about 20 seconds longer to test the sg

    Realize this is not the kit you have...but I have become a big fan of the Salifert test kits....they use a titration method for testing - and I have found that its easier for me to ensure an accurate test that way - and by accurate I mean repeatable - ie - I do it the same way every time - I guess technically the result could be wrong every time - but I consistently get to that same right/wrong answer with the salifert kit because of the method employed in the kit....and hey...there is something to be said for consistency.

    Can you tell me a little more about the tritration method please?

    TIA

    So what are your actual ALK and CAL readings with the hannah now that you have correct syringe?

    Alk 8.8 and Ca 407. I need to run my alk lower since I run such a low bio-load. My corals do better at 7-8 alk and burn at 9.

    I expected with the addition of 4 clams over 2 inches each, the development of coralline algae all over I needed to increase my dosing, this was incorrect. The tank is not yet old enough to require or need an increase in alk or calcium to the degree I anticipated. Not chasing the numbers and trying to dial it in has turned into a conundrum for sure.

    I am saving the above message.... :biggrinbounce: especially so I can show my wife that some women CAN admit when they are wrong! HA HA

    I use it as well. Works fine but yes need EXACT measurements. Also the container I use for my RO when I am testing, I have kept - STRICTLY RO for the Hanna.

    Men!!!!!!Oh I am wrong a lot more than I like to think.


    Yes I use a designated RO container for testing and cleaning all testing syringes, tubes.. blah blah blah. My BF last night "Chery you've been testing for almost an hour" oh well, I need to be precise or else.

    Looking at controllers, Apex has a much better reputation then all others, like Reefkeepers. I know this is an expensive hobby because lord I spend a ton of money but dang they ding you on everything when it comes to controllers.

    Have you looked into the reefangles? Takes a bit more work to get set up, but you get a lot of controllability for your money IMO

    Yes they do - I know there are the - I don't need a controller and the I couldn't live without a controller group. I am the latter. I could not live with out it. I cant tell you how many times a day I check it - not that I am worried but the fact that I can. I even went as far as running a line to my freshwater tank and adding an EB8, temp probe in there. Each tank has an ALS, and having the extra float switches in my overflows if I ever get a clog to shut the Return pump - that's enough for me to have that piece of mind.

    So I took a lot of chemistry like 20 years ago in college - but that was...well like I said 20 years ago....so this is my aged recollection of the description of the titration method - Titration is basically adding a measured amount of a known solution into an unknown solution to try and identify the unknown - so with salifert - you add a known reagent drop wise into your water to try and figure out the level - and you do so until it changes color - quickly and drastically (Like from blue to pink). As long as you pay attention, and apply your drops carefully, you can get a predictable result - there is much less room for error and interpretation. As opposed to a color change test - where you compare the color change to a series of other colors for known results and look for a match - which is open to broad interpretation, and things like ambient light have a greater impact on your reading.
